SPECIFICATION forming part of Letters Patent No. 560,809, dated May 26,1896. Application filed September 5, 1895. Serial No. 561,624. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE ALBERT MAN- CHESTER, a citizen of the UnitedStates, and a resident of Providence, in the county of Providence andState of Rhode Island, have i11- vented certain new and usefulImprovements in Door-Fasteners, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof, in which similar letters of reference indicatecorresponding parts.

This invention relates to door-locks, and particularly to that classthereof which are used in connection with sliding doors; and the objectof the invention is to provide an effective device of this kind, whichmay be employed in connection with sliding doors Wherever used, andwhich is particularly applicable to car-doors; and with this and otherobjects in view the invention consists in the construction, combination,and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aperspective view of my improved lock with the front casing thereofremoved; and Fig. 2, a side elevation showing the lock attached to adoor, the front casing of the lock being removed.

In the practice of my invention I employ a casing A of any preferredform, having a back B, a bottom C, ends D and E, and a top plate F, saidcasin g being in use also provided with afront side or casing, which isnot shown in the drawings. Within the casingA is pivoted an arm G, saidarm being pivotally connected with the casing near the rear end thereof,as shown at g, and arranged above said arm and mounted in bearingssecured to the back of the casing is a sliding bolt H, the bearings inwhich said bolt is mounted being shown at h. Formed on the upper side ofthe arm G, near the middle portion thereof, is a shoulder g, and formedon the lower side of said arm is a shoulder g the outer surface of whichis beveled or inclined, as shown at 9 Connected with the bottom of thecasing A is a bar K, which extends through the front side thereof, andformed thereon is an inclined shoulder is, adapted to operate inconnection with the shoulder g on the arm G,

as hereinafter described. The arm G projects through a slot d, formed inthe end D of the casing, and the outer end thereof is provided with. adownwardly-directed hook or projection L, which is adapted to passthrough an opening formed in a plate M, which is secured to the frame ofthe door or the body of a car, said frame being shown at N in Fig. 2,and the door or a section thereof being shown at O. The plate M isprovided with a projection or shoulder m, in which the opening is formedwhich is adapted to receive the hook or projection L of the arm G, andthe operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings. The pivoted barK extends through the front of the casing, and in the normal position ofthe parts the arm G is raised thereby into the position shown in Fig. 2by simply moving said bar backward under the shoulder 9 formed on thearm G. Whenever it is desired to lock the door, the bar K is movedforward and the arm G dropped into the position shown in Fig. 1, inwhich the hook or projection L formed thereon passes through the openingformed in the plate M, and the bar G is locked in this position byinserting a properly-constructed key and sliding the bolt H forwarduntil it rests on the shoulder g, formed on the upper side of the arm,as shown in Fig. 1. The bolt H is provided on its under side with anotch or recess h, in which the key operates, and whenever it is desiredto unlock the door the bolt H must be moved backward by the key, andthearm G may be raised by operating the bar K, as will be readilyunderstood. The bar G is also provided at its outer end with anoutwardly-directed extension R, in which is formed an aperture 4", andthe plate M is provided with a corresponding projection m, in which isformed a similar aperture or opening, (not shown,) and by means of thisconstruction the arm G may be sealed to the plate N in the usual or anydesired manner.

My invention is not limited to the exact form, construction, andarrangement of the various parts shown and described, and I thereforereserve the right to make all such alterations and changes therein asfairly come within the scope of the invention.

ICO

Although I have described the casing of my improved look as secured to.or connected with a door and the plate M as connected with the framethereof, it is evident that this arrangement may be reversed, and thecasing secured to the frame of the door and the plate M to the door, theconstruction and operation being substantially the same in either case.

Having fully described my invention, I claim and desire to secure byLetters Patent I The combination with a sliding door of the casingsecured thereto, an arm pivoted within said casing, and extendingoutwardly through a vertical slot formed therein, said arm beingprovided upon the upper side thereof with an intermediateupwardly-extending shoulder, and a downwardly-directed shoulder upon theopposite side of said arm, a pivoted transwardly-directed hook upon theouter end of said arm, adapted to engage a recess in a plate securedupon the door-frame, and means for actuating said bolt to lock orrelease the arm, substantially as described.

In testimony that I claimthe foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 31st day of August,1895.

GEORGE ALBERT MANCHESTER.
